INERTIA IS THE Incapability OF A BODY

TO CHANGE IT'S STATE OF MOTION OR REST UNLESS A NET EXTERNAL FORCE ACTS ON IT.

THERE ARE THREE TYPES OF INERTIA->

1. INERTIA OF REST - IS THE RESISTANCE OF BODY TO CHANGE IT'S STATE OF REST UNTIL NET EXTERNAL FORCE ACTS ON IT.

• EX - UPPER BOOKS REMAIN AT THEIR POSITION WHEN WE SUDDENLY TAKE OUT A BOOK FROM PILE OF BOOKS.

1. INERTIA OF MOTION - THE RESISTANCE OF A BODY TO KEEP IT'S STATE OF MOTION UNLESS A NET EXTERNAL FORCE ACTS ON IT.

• EX- WHEN A RUNNING BOY FACES A STONE ON PATH HE FALL FORWARDS BECAUSE THE INERTIA OF MOTION OF ITS LEGS IS BREAKED WHEREAS INERTIA OF MOTION OF ITS UPPER PART OF BODY DOESN'T BRAKES SO HE KEEPS MOVING FORWARD.

1. INERTIA OF DIRECTION - IS THE RESISTANCE OF BODY TO KEEP ITS DIRECTION UNLESS NET EXTERNAL FORCE ACTS ON IT.

• EX - A PERSON SITTING IN A CAR FACES FORCE BECAUSE OF ITS INERTIA OF DIRECTION, WHEN CAR TAKES A TURN HUMAN DOESN'T BUT IT CHANGES DIRECTION BY HELP OF CAR.
